AuraJam vs CRATELAB

AuraJam is a browser-based AI DJ that analyzes songs’ tempo, key, and phrase turns, then arranges them into a beatmatched set. Tracks can be added by dropping in a folder or pasting a link. You can change its choices by removing a record, moving a blend, or adjusting where a transition cuts. It can separate vocals and drums, and align footage to the music’s beat grid. For parties, guests can scan a QR code to request records from their phones, and the AI DJ incorporates requests into the set. AuraJam runs in a browser on the user’s GPU, needs no installation, and can be tried without an account. Its Free plan costs nothing and permits five exports a day with a small mark; on-device tools are unmetered. Pro costs $9.99 a month and includes unlimited exports without a mark and 500 monthly credits for AI generation. The site says separation, transcription, tempo and key analysis, and exports run on the user’s machine; AI video generation is an exception identified before use. The AI explains its mechanical decisions, but users judge whether tracks sound good together.

CRATELAB is AI-powered DJ software for analyzing tracks, organizing crates, planning playlists, and syncing a cloud library. Its desktop analyzer performs local beat tracking, and the site claims tempo detection to ±0.5 BPM. It identifies keys using Camelot notation, assigns energy scores from 1 to 10, and maps intro, build, and drop sections on coloured waveforms. Mix tools include AI playlist generation, transition compatibility scoring, and an AI DJ coach for suggestions. Metadata can be exported as CSV or connected through the Sync page to Rekordbox, Serato, and Engine DJ. Audio stays on the user's computer unless sent to the cloud, while metadata syncs by default. Browsing, editing, and playback work offline, but local analysis needs internet access to verify the subscription. The Free plan is free, billed Forever, and requires sign-in. Pro is $9.99 a month, billed monthly, with 200 analysis credits per cycle; each analyzed track uses one credit and unused credits do not roll over.
